There’s apparently a boner-tracking smartphone app on the Apple app store called “Morning Glory Tracker” that encourages men to report every time they wake up an erection (or “morning wood,” as it’s informally called). If you report a boner, then the app rewards you with a funny animated GIF. Wake up with an erection three days in a row, and it’ll show you a confetti-filled screen to celebrate your “boner streak.” But while a boner app might sound silly and frivolous, the app actually has a serious aim — to help track men’s overall health.

The app was launched by Roman, a men’s health app focused on erectile dysfunction, the inability to get an erection during sexual intercourse.

One of the best indicators of a guy’s overall health is whether or not he wakes up with an erection. If you wake up with morning wood, it means your blood flow and hormones are working properly, and that you’re at a lower risk for things like diabetes, heart diseases or other chronic diseases.

Tobias Köhler, M.D., M.P.H., an associate professor and residency program director of the urology division at Southern Illinois University’s School of Medicine, said that a lack of morning boners can indicate “underlying conditions like heart disease, blocked blood vessels, high cholesterol, or high blood pressure.”

This boner app is a good idea, but don’t worry if you don’t get “morning wood”

If you tell the Morning Glory Tracker that you’ve gone three mornings without erections, the app will suggest that you talk with a doctor and offer a free phone consultation with Roman’s Clinical Director. The app also keeps a calendar to help display the frequency of your morning erections for your doctor.

Dr. Köhler also says not to instantly worry if you don’t regularly wake up with an erection. He says healthy men typically get about three to five erections while sleeping (it’s called nocturnal penile tumescence), so waking up without one doesn’t mean you haven’t had one (or several) throughout the night.
